Great sound, make "whoosh" noise everytime you step on gas pedal and can hear the turbo blow off valve at work. Noticed some power gain, not sure if it's from the filter alone or with the midpipe with sportcat that I installed the same time. Great looking filter though, comes with a tiny BSR bubbled emblem on the heatsheld, looks very professional. The kit I ordered missing one small rounded rubber spacer, but installed ok. Highly recommended.
